How to purchase, renew, convert or upgrade your PDXpert license

We provide standardized products with uniform sales policies and procedures. Our customers represent a wide variety of industries, operating structures and legal jurisdictions throughout the world; we regret that it's not practical for us to examine, negotiate and agree to each organization's unique purchase terms. Please read our policies before offering to make a purchase.


Sales policies

All commercial transactions between Buyer ("you", "your") and Active Sensing, Inc. ("ASI", "we", "us", "our") are subject to the standard terms, conditions and policies ("policies") described (1) on this page, and (2) within our software license agreement. Buyer and ASI includes their respective subsidiaries, employees, contractors, and other authorized agents. Any terms or conditions that are inconsistent with or are in addition to our policies ("exceptional terms") must be specified in a written Master Sales Agreement ("MSA"), which must be signed by an authorized representative of each party prior to your purchase.

For transactions that are not subject to a written and signed MSA, any of the following constitute acceptance of our policies: (a) you have registered on this website and visit this web page; (b) we identify these policies in any written or electronic communication — e.g., quotation — to you prior to your purchase; (c) you receive an invoice referring to these policies and you pay any portion of such invoice; (d) you install or use any of our products; or (e) any other act which reasonably implies awareness of these policies. Your acceptance authorizes us, without further notice, to reject any exceptional terms however communicated. If you provide any communication that requires an acknowledgement by us, our acknowledgement (signed or otherwise) confirms only our receipt of your communication without accepting any exceptional terms contained therein. You may reject these policies by declining to purchase, or by canceling your purchase order.

A PDXpert software license specifies "named user accounts"

PDXpert software is licensed for a specific number of named user accounts. A named user account is one person who is assigned a unique log-in username (along with a security role and optional password). PDXpert software is not licensed for concurrent, shared, floating or other multi-access user accounts.

When a person no longer needs access to PDXpert, the administrator can delete that person's named user account, and re-assign the account to another person. Although each person must have a unique username, we do not maintain a record of the actual persons or their assigned usernames.

A maintenance, support and upgrades (MSU) subscription is assigned to a license and all of its user accounts. It's not possible to assign MSU to a subset of user accounts on a license.

Purchasing your PDXpert software license

You may provide your purchase order via email, fax, postal mail service, or telephone. We recommend always sending an email, even when sending your order via other means, so that we may confirm your order and issue your license as quickly as possible.

Ensure that the purchase information includes your organization name, address, postal (zip) code, and country, as well as the email and telephone of the principal administrative contact(s).

US and Canada

For most customers in North America, we are pleased to offer payment terms of NET 30 DAYS. Upon receipt of your purchase order, we provide a license key that provides temporary access for 35 days, and will email your final license key immediately upon bank receipt of funds.

Other countries

For many international customers, we can immediately issue a temporary license key against your purchase order. Payment is due immediately upon your receipt of our emailed license key and invoice.

Taxes and government-imposed fees

You are responsible for paying all applicable government sales, transfer, use, asset, import, customs, value-added, and other taxes, tariffs, duties and fees imposed by any governmental entity.

Non-tangible computer software, such as PDXpert software, is not subject to Colorado state sales tax.1

Credit reporting

You authorize us (a) to obtain and verify credit reports and other credit information from third parties to ascertain your suitability for credit payment terms, and (b) to report your payment performance to our banking and credit services providers. Failure to honor the agreed payment terms will affect future transactions.

Brokers & purchasing agencies

If you are a purchasing or financing service that is handling the transaction on behalf of another company, you must indicate the full contact details of your principal. Our software license requires acceptance by the company that actually installs and uses the product; we will not issue a license in the name of an intermediary or broker.


By check: Checks are payable to Active Sensing, Inc. and must be for the total invoice amount in US dollars. Currency conversion fees, bank fees and other transaction costs are payer's responsibility. Mail to:

Active Sensing, Inc.
Attention: Accounting Dept.
P.O. Box 1236
Castle Rock, CO 80104-1236 USA

By wire transfer: Wire transfers must be received into our account (a) for the total invoice amount in US dollars, and (b) free of all transaction costs such as currency conversion fees; SWIFT fees; service surcharges; government taxes, duties or forex fees; or other charges. Contact us for correspondent bank information.

By PayPal: For your convenience, prior to the payment due date we can re-issue our original invoice as a PayPal invoice sent to a designated payer (email address). A 2% convenience fee is added to our original invoice total. Payment method — debit card, bank transfer, credit card, PayPal balance, etc. — is agreed between PayPal and payer. PayPal is an independent entity; we do not determine (or even know) the criteria for a completed transaction. If payer's transaction cannot be completed, we will cancel the re-issued invoice and restore the original invoice, including original amount and due date.

Renewing your perpetual MSU or subscription license

License keys expire on the ending date specified by the license. Your software license type — perpetual or subscription — determines the license duration and expiration effect.

  • Perpetual license: Your renewal of annual maintenance, support and upgrades (MSU) ensures continued access to new software releases, application information, and technical support. If you choose not to renew your MSU, you'll still have access to the PDXpert system, but you can no longer update your software to the most current release.
  • Subscription license: For continued access to the PDXpert system, you must renew your subscription by the expiration date.

Your license renewal price is calculated using the quantity of user accounts specified in the current PDXpert Software License Key, multiplied by the currently-published rates & discounts for the license.

A new license key is issued when we receive your renewal payment. To avoid interruption in your service, you can request a renewal invoice to be sent about 30 days (or any other period) before your license key's expiration date. For established customers with a good payment history, we may issue the license key immediately upon our receipt of your confirming order.

Purchasing additional perpetual user accounts

If you have previously purchased a perpetual license, additional user accounts are discounted based on the revised quantity of user accounts, which includes all previous user accounts purchased.

For a perpetual license with a current MSU subscription, we will synchronize your new license's MSU expiration to the previous license's expiration date and invoice you the prorated MSU amount in addition to the new perpetual license. When the MSU is renewed the following year, the total of all user accounts (whenever acquired) determine the discount level.

For a perpetual license without a current MSU subscription, you can purchase additional user accounts provided that the new accounts are also purchased without MSU. Since all clients must be of the identical software release, your new license will be compatible only with your previous license's software release. If you simultaneously upgrade your older license, you can install the latest release for all users. Alternately, we'd be happy to calculate the cost of adding MSU for all user accounts.

Purchasing additional subscription user accounts

If you have previously purchased a subscription license, all incremental user accounts are discounted based on the revised total of user accounts. We synchronize your new license's expiration to the previous license's expiration date and invoice you the prorated amount.

Converting from a subscription to a perpetual license

You may convert an unexpired subscription license to a perpetual license. We prorate the current subscription and apply the remaining unused portion to your new perpetual license and MSU. An invoice is issued for the difference between the cost of old and new licenses; an unused portion that exceeds what can be applied to the new license is not refundable.

Converting between full-function and read-only accounts

At your option, we can convert one full-function (FF) user account into several read-only (RO) user accounts, or vice versa. Perpetual licenses are converted 1FF:5RO and subscription licenses are 1FF:4RO.

The license MSU/subscription expiration date will not be affected. As a result of this conversion, your user account discount level may increase or decrease: no discount adjustments will be made for the current MSU/subscription period, but subsequent renewals may have a different discount level.

Conversions are subject to a US$100 service fee; however, we'll waive this fee if you haven't made a conversion within the preceding 12 months.

Calculating the price of a perpetual license and MSU

Here's how we calculate your perpetual license price and annual MSU subscription.

We determine (a) your discounted perpetual price based on the number of user accounts you've chosen, and (b) if you've opted for MSU, add the MSU rate for that discount level. We then (c) multiply the result by the actual number of user accounts you've selected. (d) For the MSU expiration date, we increment the start date's year.

For example, suppose that you purchase a perpetual license for 6 users on April 10 and you choose to include annual maintenance, support and upgrades. We calculate the total cost (a) using the one-time price per user from the 5 user discount cell, (b) add the annual MSU cost per user, also from the 5-user discount cell, and then (c) multiply this result by the 6 user accounts. (d) Your MSU expiration date is April 10th next year.

Calculating the price of a subscription license

Here's how we calculate your subscription license cost and expiration.

We determine (a) your discounted price based on the number of user accounts and the commitment period. (b) We then take the monthly rate, multiply it by the number of months you've selected, and (c) multiply the result by the number of users you've selected. (d) For the full year, we increment the start date's year. For fractions of a year, we increment the start date's month.

For example, suppose that you choose to start a subscription for 8 users on April 10 and you want the subscription to run 6 months. We calculate the total cost (a) using the monthly price per user account from the 6 month/5 user cell, (b) multiply this cost per user by the 6 month discount period, and then (c) multiply this result by the 8 users. (d) Your expiration period is 6 months after April 10th, which is October 10th.

All subscriptions are paid in full at the beginning of the subscription period. Discounts are based on your revised user account commitment, which includes all of your currently-active accounts.

An established subscription cannot be reduced prior to its expiration, and the subscription fees are not refundable. However, you can renew a subscription at its expiration for a shorter period or for fewer users. You can take advantage of additional discounts by adding users and/or extending the subscription period while the subscription is active. You can also purchase a replacement perpetual license at the end of any subscription period.

Upgrading older perpetual licenses without MSU

If your perpetual license's MSU subscription has expired or you never subscribed to MSU, you may still be able to upgrade your users to the current release at a discounted price. Your current perpetual license registration displays a Subscription ends or Expiration date that determines the discount that can be applied to our current published price. The license also specifies the number of user accounts that can be upgraded at that discount level.

Time after "Subscription ends" date within 1 year 1 to 2 years 2 to 3 years >3 years
Reduce perpetual license per-user price by 65% 40% 15% 0%

At the time you purchase an upgrade, you can also purchase a new MSU subscription at the published price to keep your software maintained, supported and upgraded for an entire year.

Multi-server environments

Each complete PDXpert system includes a license for the PDXpert Application Server software, which is bundled with your PDXpert client software at no additional cost.

Volume discounts are offered on a per-server/per-system basis that counts the number of user accounts attached to a licensed server. For companies with multiple systems (and server licenses), each system is treated separately for determining eligible volume discounts.

Moving user accounts between systems, or merging one license into another, is subject to a US$100 service fee, plus any proration required to synchronize the moved accounts with their assigned license's expiration. As a result of this move, the new user account discount level may change. Although no discount adjustments are made for the current MSU/subscription period, subsequent renewals may have a different discount level.

Maintenance, support and upgrade scope and warranty

Our maintenance, support and update ("MSU") service is available as an option with perpetual licenses, and is included with all subscription licenses. MSU services are limited in duration and must be renewed periodically to maintain coverage.

The scope of MSU services:

  • Maintenance updates our software installers and code in response to changes in the Microsoft Windows computing environment. The computing environment is comprised of supported 32-bit and/or 64-bit versions of: Microsoft Windows, Windows Server and .NET; SQL Server versions and editions; security notices and service packs for Windows, SQL Server, .NET and Windows Search; and third-party components that we may provide with our software (e.g., OpenXML, Lucene, SQLite). You agree to maintain your computing environment in accordance with our published system requirements, which may change from time to time. We agree to make commercially reasonable efforts to respond to computing environment changes in a timely manner.
  • Support provides web-based, telephone and email assistance covering system installation, configuration and operation to up to three designated system administrators, and application training to other users. You agree to provide us with the necessary access (for example, to log files and database extracts) required to fulfill our support obligations. We agree to make commercially reasonable efforts to promptly resolve product support requests.
  • Upgrades add new features to, improve the performance and convenience of, and correct reproducible deficiencies in the product. The nature and schedule of product upgrades will be determined at our sole discretion. We agree to make commercially reasonable efforts to ensure that the software product, its documentation and upgrade release notes  conform in all material respects to each other. We also agree to make commercially reasonable efforts to ensure that data contained in an earlier release can be upgraded to a new release at nominal cost.

MSU does not include: on-site visits; legacy data import services; installation, support or interfacing of third-party hardware or software; training third parties in our product's configuration or use; designing, maintaining or updating "data transformations", "views", "scripts", or other custom computer code or data specifically developed to meet your requirements or provided as an example; database repair due to (a) application misuse or failure to follow practices described in our documentation, (b) non-conformance of imported data, or (c) data modification by software other than our own (e.g., third-party applications); any Microsoft product for which its Mainstream Support has expired; and other products or services that we have not specifically included. At our discretion, we may waive any of these limitations and exclusions on a case-by-case basis, and such waiver does not constitute a future obligation regarding these limitations and exclusions.

All product changes are incrementally and cumulatively added to our most recent published product, and not to any older product that you use. We will periodically announce, according to our standard policies, new product releases that we make available for download. When we make a new product release available for download, you agree that the new product (a) becomes an integral part of the original product, and is subject to the terms of the PDXpert License & Warranty Agreement, and (b) fulfills our applicable maintenance, support and/or update obligations, regardless of whether you choose to use it.

We warrant that product and documentation delivered under an MSU subscription substantially conforms to one another. You agree to notify us of any deficiencies within 30 days from our delivery of a new MSU product release.


Unless otherwise agreed in writing, these provisions apply to separately contracted professional services outside the scope of your MSU subscription (e.g., custom data transformations, database maintenance activities, PowerShell scripts).
